This B+B dew formation probe is a combined sensor which consists of two single sensors. A resistive dew sensor in thick-film technology reacts to high relative humidity values (approx. 93 to 99% RH). A second conductance sensor embedded as interdigital structure on a carrier substrate detects possible condensation. In combination with these two methods a safe switching performance is carried out.

Therefore the probe is also suitable for critical applications such as in cooling ceilings. With the universal sensor switching module SENSW-MOD12V, SENSW-MOD24V, SENSW-GEH230V the B+B dew formation probe is an optimal dew protection switch.


  • Automatic ventilation control in sanitary facilities, showers or indoor swimming pools,
  • As humidity monitor for exterior walls, pipelines or cellar rooms,
  • Monitoring of cooling ceilings, shop display windows or humidity in switchgear cabinets
